To .all whom-t may concern,.-

Beit known that I, Louis STEINBERGER,

a citizen of thepUnited States, and a residentIf of the. city 'of New York, borou vh of Brook- Alyn, m'the county of Kings and tate of New York, have 'invented ainew and Improved High-,Tension Insulator7 of which the followminoreparticularf'object being to produce`a tions where such a-full, clear, and exact description.y .l

invention relates to insulators, my

type ofhigh tension insulator suitable for heavy currents and adaptedto prevent arcrt under condi-i ing'from the lineto thesu mig t otherwise take --I .also provide''a lu-rality of supporting portions'for theodn uctor', and also provide means 'for su porting, simultaneously, a plu-*f ralityo-'con uctoru On'thesame insulator.

Among'. `the'severa objects presented by my invention the following: 1.' To give the insulatorga'- composite structure so that it maybe assembled -withoutgthe necessity Jfor handling pieces `of;excessive weight; 2.y To

confer a great amount of mechanical strength -by the use of a comparatively small quantity of material; 3. .To yenable ldiiferent parts of 1 the insulator to each ser-ve as a com lete insulator whenever'necessary ordesira le 4. To

fit the-supportin pin with thelower hood in ysuch manner t at the latter 'rests upon a comparatively broad bearingsurface `5. To

prov-ide an insulator havinghoods ofgcornparatively large surface, so as to adapt itfor supporting conductors carrying currents of -very high potential; 6.' To rovide a num'- ber oi' restsrforV supportin t e conductor or conductors; 7.-'To make t e several'parts of the insulator separable sothat either of the parts may be readily replaced when injured -or' destroyed; and'to achieve certain otherelectrical andv mechanical objects increasin fthe general efficiency of the insulator; an

.y .8. To provide-an insulator with means for supporting, simultaneously, a plurality `of conductors. y l C vReference is tobe had tothe accompanyingdraWingsorming apart of this specigiication, in Whlch similar characters of'reference indicate corresponding parts in all the figures', `ligire 1 is a plan view of the insulator ready for use; Fig. 2 is a central vertical section through the same, upon the line 2,-2- lookingtoward the top of lthe drawings Eigy' 1era perspective view of the lower insu- ,..latorbodywhen*removed from the support'- v are of such conformit ing pin and disconnected from the upper hood.

A The supporting pin is shownat 4 and -is provided with a conoidal portion'5 having an annular lowery surface 6 and an annular -spheroidal upper surface 7 ,from the center. of which projects a vertical boss 8 threadedl externally. The insulator. body 9 is pro-f' vided with an annular skirt 9a and is of such conformity as toiit upon the spheroidal surface 7. The insulator body 9 is also provided with a number of radial supporting ribs 10, each terminating'at its' upper Iedge in a at `surface-11, and with an annular skirt 10d integral therewith. Integral with the in7 sulator body 9 is a boss 12 rovided externally with a thread 12, an with a slot 14 extending diametrically across'its top, as indicated in Figs. 2 and 3. An annular groove 12b'encircles the boss 12 andmay be used for retaining a tie wire. A hood is shown at 15 and is provided upon its under surface with an annular channel '16, boundedby an annular bead17. This bead rests u on the fcur. outer ends 11'a of the radial ri s 10. The hood 15 isprovided' with a boss 18 integral therewith, this boss having a diametrical slot 19 and being encircled by an annular channel 20, in which the tie wirenmay be placed. .The cable or conductor normally rests in the slot 19 of the hood 15,-and is held in position by a tie wire in the groove 20. If, however, this part be broken away or destroyed from any cause,` the cable or conductor may rest within the slot 14 of the body portion 9 and be confined by a tieiwire in the annular groove 12b, The ribs 10 are pro` 'vided with notches 10a, 10b, 10,into an one of which a conductor maybe su porte More than one conductor may be t us supported; as, foriinstance, 1n casea number of insulators or insulator pins be disabled by a stormfso that several conductors -happen to bereleased. Itis `also desirable to support several conductors upon the same insulator in instances where some of these conductors are used for absorbing the effects of induction from extraneous Wires. The 'notches '10%10, 10c also increase the surface over which'leakage tendsto take place, and they therefore diminish the surface leakage. The annular groove 12b also tends to diminish.

surface leakage.' The supporting ribs 10 part of theweight of t e hood 15 upon their upper edges 11, 1,1. .VrThese supporting ribs that they receive a .IOO

lio

mechanical strain due to the superim osed weight, 1n such manner that the strain v1s distributed as equally as possible. ,The 4upper' surface 7 so engages the spheroidalsurface- 921 of the body portion 9, that in case of a relative movement between these parts the possible.

base portion of insulating material will iit neatly uponthe surface 7 wherever engaging the same. This arrangement also serves to distribute thestrain as lnearly equal as I do not lirdit myself tothe exact form nor to the details'o'f any or all of the parts above shown and described, nor do -I limit myself to anyparticular combination` of the parts,

nor tothe use of any prescribed materials.

I prefer, however, to employ'the insulating material known in the art as electrose It will be evident to those skilled in the art that many changes in the construction, form, and arrangement ofthe parts may be resorted to without departing from the spirit or scope of my invention. v Having thus described my invention, I 'claim as 'new and desire to secure by Letters Patent 1.
